Shadow Woods-CS 900212February 12, 1990 To: From: Re: Dale Jackson, Building Official Road COPPEL PUBLIC WORKS MEMORANDUM / ~ OF COPPELL FEB 1 1990 Retaining Wall on Existing Parallell to Coppell This is to provide you information that we have no objection for the proposed timber wall to protect the trees in the temporary drainage easement parallell to Coppell Road. As per the attached letter by the design engineer, as long the wall does not pertrude or extend on the existing road drain ditch for Coppell Road then there would be no objection. Additionally, any wall should not be built to obstruct any other drainage such as side yard drainage on these lots along Coppell Road.

February 8, 1990 Mr. Russell Doyle City of Coppell 732 DeForest Coppell, Texas 75019 Re: Shadow Woods Estates NDM Job No. 88-10-116 Dear Russell: It has come to our attention that the developer of the above referenced project desires to construct a retaining wall generally along his east property line adjacent to the western road ditch for Coppell Road. Please be advised that it is our belief that as long as the wall is located near the top of the bank of the ditch such that the water carrying capacity of the ditch is not meaningfully dimished, there should be no problem created by this construction.
